Questions about the Stereolithography (SLA) method of 3D printing.

For questions regarding troubleshooting, design, maintenance, etc. for the 3D printing method of Stereolithography (SLA). With this production process, parts are formed in a layer by layer fashion using photochemical processes by which light causes chemical monomers and oligomers to cross-link together to form polymers.

Why is CLIP so much faster than SLA?

Stereolithography produces parts by projecting ultraviolet light on the top of a vat of liquid photopolymer, causing it to harden. CLIP produces parts by projecting ultraviolet light through the bottom of a vat of liquid photopolymer, causing it to…

Can SLA printers produce strong engineered parts?

I have an FDM printer, I printed ABS for years. Since SLA printers became really cheap lately and are able to print finer details, are there resins out there as strong as ABS/PLA?

Using heat-set inserts with SLA printed part

I have an SLA printed part I want to put a brass threaded insert in using a soldering iron. The insert is slightly larger than the hole so I would assume the edge will melt and re-freeze around the teeth. Are there any issues with melting SLA or…

What materials would be appropriate for pool parts (chlorine & UV exposure) using SLA or FDM?

I've got a printer on the way later this year that's supposed to be able to do both FDM and SLA (with the appropriate accessories). I'm interested in printing some parts for swimming pools (the types that generally cost fifty cents to make, but with…

Toxicity of Light-curing resin?

I'm one of the lucky (??) Kickstarter supporters who received a T3D resin printer. This uses a proprietary (so far as I can tell) resin which cures under exposure to visible, rather than the usual UV, light. The manual is full of dire warnings…

Methylated spirits or turpentine to clean resin printer?

I'm new to 3D printing and have bought a resin printer. Cleaning with Isopropol Alcohol seems to be the rage, however I think this is unaware of cost savings. It appears methylated spirits is ok and is 25% the cost of Isopropol Alcohol. I'm now…

How does a UV LCD 3D resin printer work?

I've been wondering this for a while, and have searched for hours and have found nothing except undetailed explanations and projects. How does a UV LCD 3D resin printer cure resin exactly? I understand there is an LCD screen, but where does the UV…

Sparkmaker SLA resin not curing

My model layers are printing much as I expect but the parts when removed from the plate are very soft and flexible and fail to harden any further in sunlight or UV lamplight. A tall or slender part will bend and distort under its own weight while…

Which choices do we have on Daylight Resins?

I'm planning to make an LCD Resin printer. I'm still learning and I found out that I need daylight resin (which hardens when white light comes from the LCD). If I search for "Daylight resin" on Google, the only "useful" result I find is for…

What is the lifespan of a SLA Resin Tray?

As far as I know resin trays have a Teflon coat that allows prints to stick to the build plate easier than the resin tray but this Teflon coat wears over time. I am new to the SLA scene and am currently troubleshooting a Draken Facture and trying…

SLA printers: food-safe resin parts

I've actually read that resin printed parts are not food-safe in Reddit and Formlabs guide. However, it also says that food-safe can be achieved applying some kind of food-safe coat to the printed parts, or even printing with ceramic resin. As an…
